Improved cattle-pood



JOHN T. HARRIS, OF TYNGSBOROUGH, MASSACHUSETTS.

Lam Patent N 96,317, dated November 2, 1869.

IMPROVED CATTLE-FOOD. l

The Schedule referred to in these Letters Patent and making part of the same.

'distillcries, commonly known as mash or grains, and

converting these products, with other substances, into a cattle-teed ma solid form for transportation.

I obtain the gluten or saccharine matter from the maize or Indian-corn plant,-and other vegetable sub stances, in the manner described in my specification finztreating and utilizing this plant, and reduce it, by evapm'ation or otherwise, to a semi-liquid state, and, when in this condition, convey it, by any suitable means, into a mixer or pug-mill, into which is introduced, at the same time, herbaceous substances, cut into short lengths, or chaff, such as grass, hay, or straw, or filrinaceous substances, 'in such quantity as will absorb the semi-liquid gluten, or saccharine matter, and form a moist composition of matttr.

The pug-mill being in motion, the mass will be thoroughly mixedor blended together, and, while the process of mixing is going on, I add to the mass a proper quantity of aromatic substances, and a suflicient amount of common salt, which acts as a prescrvative, and also imparts flavor to the mass.-

The mass, when thoroughly mixed, is passed to a luick-machiue with altered moulds, and pressed into blocks, which are conveyed to a kiln or drying-room,

and, when dried, are ready for use and transportation.

The spcntmat-ter from breweries and distilleries, after distillation, is conveyed to a centrifugal extractor,- of any form, a self-disclu rging one being preferred, and, by this means, the liquid separated from the solid pordoubt this spent matter, the liquid port-ion descending into a tank or receptacle beneath the extractor, to be conveyed, by any convenient means, to an evaporator, for the purpose of reducing this liquid to a semiliquid state, and to dispose of any alcohol or spirits it may contain. tank supplied with steam-rapes.-

, This semi-liquid substance is conveyed into the pug-mill, with the solid portion, that has been betbre separated from the liquid portion of the spent matter and herbaceous substances, such an straw, hay, grass,

8%., cut into short lengths or chatf, by an ordinary This may also be accomplished in a straw-cutter, in such quantity as will absorb the liquid portion and form a moist composition of wetter,'is added.

The aromatic substances, and common salt,-in the same quantities, and for the same purposes-as herein before stated, are also'added, and when the mass is thoroughly mixed and blended together in the pug mill, it is then passed through the brick-machine, as before described, to form it into blocks, which are conveyed to the kiln or drying-room, to be dried, when they are ready for use or transportation. I do not continemyself to the use of a pug-mill for mixing or blending the mass together, as this may be done in a vessel constructed of either wood or iron, revolving on an axle, with arms or stirrers, and

of conical or other shape, supplied with man-holes, for the inlet and outlet of the material or itmay be done by any other suitable mechanical device. Neither do 1 confine myself to the use of the brick-ma.- chine for pressing and forming the mass, as this may be done by any of the many forms of machinery applicable for this purpose.

I am aware of R. L. Delissers patent, April 21,

1863, No. 38,220, reissued September 25, 1866, No.'

2,365. This is a patent for the manufacture of paper "from the fibres of corn by a particular .process, the.

glutcnons or nutritive. portion being eliminated from the plant by means of a heated alkaline solution, and, as a consequence, a. portion of the alkali remains with the glutcnous matter after the same is-separatcd from the plant. .Practice has shown that when in this condition, the material, when dry, is too hard and solid to be valuable for this purpose. .In my invention, the glntcnous matter being separated by entirely mechanical means, is utilized in apeifectlypin'e state.

i desire. to embracein this specification only the cattle-teed, herein described, that is tosay, made of the gluten obtained as herein described, by purely mechanical means, umnixed with chemical substances, and mixed with tarinaceons, vegetable, and other mgrcdicnts, as set forth.

l'do not claim a cattle-feed where the gluten 1s extracted by a chemical process, as this is not new.
